PRINTING MACHINE.

Application med `.mnuary l25, 192e. ser1a1 No. 83,451.

This invention relates to oiiice printing machines primarily adapted forprinting on envelopes, cards, tags and the like. The primary object ofthe invention is to provide a simple and efficient means for enablingready change of the printing characters or a portion thereof as desired.More particularly it is an object to provide a segmental type holdercarrying arcuate lines madev up of individual type, means which will notcomplicate the segmental holder being provided to retain the lines invplace and allow their removal for the purpose `of quick change of theform setup; and generally it is an object to render the constructionsimple and economical in manufacture and etlicient and durable inservice. y

My printing machine is well adapted for cancelling stamps, as it isadapted to operate equally well on articles of various thicknessesarranged indiscriminately. The machine however may with advantage be putto other uses.

A. convenient embodiment of my invention is illustrated in the Vdrawingshereof, and is hereinafter more fully described and the essentialcharacteristics are summarized in the claims. i

Fig. l is a front yelevation of my printing machine; Fig. 2 is averticalcross section, as indicated by the line 2 2 on Fig. l.; Fig. 3 is avertical longitudinal section,as indicated by the lineB-S on Fig. 2;Fig. a is a detail of the inking roller and its support,-being averticalr section on the line 4 4 on Fig. 2; Fig. 5 is a detailillustrating the support of the paper detecting lever, being a verticalsection. on the line ll-l on Fig. 2; 6 is an `elevation illustrating thedetector coni trol 'of vthe eccentrically Vmounted platen, being avertical section on the line 6-.6 on Fig. l looking toward the right;Fig. 7 is an enlarged vertical cross-section of the rotary printingmember, as indicated by the line 7 7 on Fig. l; and Fig. 8 is a. detailillustrating a system loi latches for retaining the removable printinglines, being a section substantially on the line 8,?-8 on Fig. 7 butpartly broken away.

rl`he frame nf my machine is shown as ccnsieting ejf a pair ofuprightend plates i0 il, a connecting front cross plate L?.

and certain cross rods. Journalled in the end plates is the main shaft20 on which is' that it may give back from the platen according todilferent thicknesses of material fed between them. The drawing shows aneflicient means for accomplish-ing` this, which however is not claimedin this application, but in my preceding application No. 30,658 filedMay 16, 1925. As shown, I mount a double arm 24 and 25 having a hub 22to the other end of which is secured a disk 23, as by screws.- Thesegment 30 near one end has an inward ear 31 which liesbetween the disk23 and the arm 25, and a pin 32 occupying these parts pivots the segmentto the rotatable member. I j f Y To a block 33, rigidly bolted to theinner face of the segment near its other end is pivoted a rod 34 whichextends `loosely through a head 35 'carried by the rigid arm 24. Nuts 36on this rod limit t-he outward movement of the segment while a compression spring 37 surrounding the rod between a head 38 thereon and the,head 35 yieldingly holds the segment lin printing position but allowsit to give back according to the thickness of the material fed betweenthe segment and platen.

yThe segment is provided with overhanging parallel rails 40, providingVundercut channels adapted to retain grooved type T. To allow the typeto be readily slid into place between the rails and locked therein, Iprovide the mechanism shownin Figsj? and v8, comprising a'system oflatches for the respective channels between the rails.l As there shown,l mount a series of'blocks 422 in thespace 43 between the segment properand a radial portion of the block 33 to which the rod Se is pivoted.`Eachof these blocks position.

or with the transfer tool which delivers the type or receives it fromthe segment. When a block 42 is pressed inward (as shown in the c ase ofone block in Fig. 8) the corresponding channel is free and the type row,or a portion of it, may be installed orremoved, after which the blockreturns to loclr it to At the other end of the channels I prefer tomount a stop 48 shown as an L- shaped bar of metal held by a screw 49.'The construction described enables the type to 'be very readilychanged.

lTheplaten 52 with which the segmentcofacts is shown as a long rollermounted on the shaft 5 which isl connected by gears 60 and 61 Vwith thevsegment shaft 20. l have shown arhand crank 65 mounted on'a. stud at one"end ofthe machine and carrying` a gearg meshing with a gear 67 on thesegment shaft, and this is a convenientway of driving the machine byhand power.

I have shown mechanism preventing the operation of the machine whenpaper is omitted. y p

`As shown in Fig. 3, the platen shaft 50 is mounted at one end adjacentthe segment eccentrically lin a bushing 7 0 which is rotatably mountedin the frame member l0. On

'this bushing is-an'arm 7l 6) pivoted to a flat bar 73 slottedabout thesegment shaft 20. "This bar carries aroller 74 coacting with a cam 7secured to the segment disk 23. Accordingly, each rotation of the`segment `shaft turns the eccentric to raise that' end of the plateninto vposition to be active, this being the position shown in Fig. 6. Asthere shown, the platen is raised, while theprinting segment 30 is outof registrationv with theplaten. Now, unless the paper' detector acts by reason of the presence of paper, the cam will pass beyond the rollerand the slide will'be freed and the spring '76' thereonwill restore theplaten to idle position.

The paper` detector mechanism comprises alglever or finger 8O pivotallymounted on a 'longitudinal rod 8l and connected with a roclarm 82 whichis adapted'to'be'ar against a dog 84 pivoted at 85 to the frame ofthemachine. The upper end of this dog stands normally opposite, but freefrom, a notch 7 8 in the slide-70, being retained in this position byaspring 86. When no paper is present, the (detector mechanism describedis idle.

The 'finger 80 it will be noticed', extends shaft 8l.

into a peripheral groove 54 in the platen, so that it is impossible forpaper to be fed to be gripped above the platen without raising thelever. Then the linger isso raised it rocks upwardly on the arm 82 whichthus roclrs the dog into the notch 7 8; thereafter when the cam 75clears the roller 74,

the slide cannot return to its normal downposition but is held by thedog, and thus the .platenis maintained in its active position throughoutthe time the segment is moving past the platen whereby printing iseffected.

.To prevent jamming ofthe parts and allow the linger 8O to be raised atany time irrespective of the position of the notch 78 with reference tothe dog 84, l connect the dog tripping arm 82 yieldingly with thedetector linger 80. As/shown'in Fig.' 5,the detector arm is pinned to ahub-'87 on the Pinned to the other endet ythis hub is a short rock arm88 which is connected by a spring 89 with'the dog-operating ,l

arm 82.vv This spring 89, is stronger than the spring S6 acting ony thedog. Y ltrwill be seen that if the detector, arin 80 is raised at a timewhen the notch 7 8 is opposite the dog 84, the two armsSS and 82 act aunit, swingingythe Vdogfinto the notch. If however, the detector yarmfis raised at any other time the spring 89 is constrained, forcing thedog against the edge of the slide 70 so that it will pass into the notchas soon as the notch comes oppo- Vsite the nose of the dog; l

In the interest of simplicity, Iprefer te provide the eccentric bearingdescribed for only Vone end ofthe platen. find I' can eifect this byallowing a slight looseness of. lit of theplaten shaftvwithV its bearingin the standard 1l. rThe platen shaft is parallel with the segment shaftwhen theplaten is raised'into active'position, and the slight divergencefrom parallelism' whenV theQpl'at-Vl en isinactive is immaterial.

Fig. 2 illustrates a. simple elasticv stop limiting thel hand-fed sheetuntily it is gripped by the segment andplaten. This elastic stopcomprises a spring 'linger -100 mounted on a frame rod lOl and acooperating spring pressed lingerJQ- mounted on a frame lrod 103. rlhislatter finger is preferably pivotally mounted on a bloclr 104 which isadjustably clamped tothe rod by 'a screw 105;" A spring 106 mounted inrecess in the block forcesthis linger against the linger 100.V Asuitable reeess'@ in the platen accommodates the engaging ends of thesefingers.` A' "r i The paper is normally'ied by handalon'g the papertable 10S until stopped by the engaging ends et the lingers '100 and102'. In this same movement, the forward edge of the paper raises thedetector arm 80 which thus, by the mechanism already described, operatesto hold 'the platen in its raised po- CII sition, after it has beenraised by the'cam mechanism. Thus the paper may be advanced by hand atany time, and, at the proper time, it is picked up by the machine, fedthroughit and printed; while it, for any reason paper is absent, theprinting member and platen remain out of contact.

Figs. 1, 2 and 5 illustrate a convenient paper ejector. This comprises aroll 110 on a frame rod 111 and a surmounting roll 112 carried in thesheet metal cage 115, pivote-d on the rod 81. This cage is pressed down-Wardly by a spring 118 which is mounted within the cage has one endanchored to the rod and the other to the cage.

To ink the segment I have illust-rated the telt roller 120. This is`shown as comprising felt disks mounted on a hub 121 which has a hollowbearing sleeve 112 mounted on a stud 123. This stud is carried by ablock `124 mounted in a recess 15 in the inner face of the frame member10. The block is slotted and a pin 125 passes through the slot andthrough the frame member and has on its end a wing nut 127 to lock theparts together. Thus the block may be adjusted toward or from theprinting member, bring ing the inking roller into proper position withreference to the segment, and the wing nut then locks the parts in thisadjusted position. I may replace the inking roller without changing itsmounting, by vsimply removing a pin 128 from the stud 123 and slidingoff the complete inking roller.

Having thus described my invention, I claim 1. A printing member havingadjacent overhanging parallel rails providing an undercut channelbetween them, a slidable block, and a. spring normally maintaining itopposite the end of the channel, said block being movable to allowaccess to the channel.

2. In a printing machine, the combination of a printing member parallelundercut type channels on the ace of the member located close to eachother so that all may hold a unitary form, and a series of adjacent,individually movable locking blocks one for each channel.

8. In a printing machine, the combination ot' a printing member,parallel undercut type channels on the face of the member, a series oflocking blocks one for each channel, and a series of springs formaintaining said blocks normally across the ends of the re spectivechannels.

4. In a printing machine, the combination of a rotary carrier, a segmentadjacent its swinging end thereon pivotally mounted at one end andhaving on its convex face a series of arcuate parallel undercut typechannels,

signature.

and a series of locking blocks one for each channel movably mounted onthe segment.

5. In a printing machine, the combination of a revolving segment,parallel arcuate rails mounted on the Jface thereof and havingoverhanging edges, a stationary abutment at one end of the channels asprovided, a series of individual abutments at the other end comprisingslidably guided blocks having pins connected therewith, and slidable inthe openings in the carrier, and spring surrounding said pins andpressing the blocks toward the ends ot the channels.

6. In a printing machine, the combina-tion ot' a` rotary carrier, asegment pivoted therein, a spring for pressing the segment out- 'wardly,parallel arcuate rails mounted on the face of the segment, a series ofindividual blocks slidably guided substantially radially on the segmentadjacent the ends of the channels, springs pressing said blocks normallyinto position to overhang the channels, there being clearance enablingthe blocks to be pressed inwardly against the action of the springs tofree the channels.

7. In a printing machine, the combination of a carrier having anundercut channel in which a row oi grooved type may be mounted, amovable end gate for the channel, a spring pressing said end gate in adirection toward the plane of the face of the type, and a stop to limitsuoli movement of the gate, the gatel being movable aga-inst the actionof the spring to free the type.

8. In a printing machine, the combination of a carrier having parallelrails providing adjacent undercut type channels adapted to hold rows ofindividual type to make up a Ytorm, and individual means for lockingeach row independently on the carrier, said means being movable to treesuch row.

9. In a printing machine, the combination oi' a printing member havingparallel rails with overhanging edges adapted to hold between them rowsof grooved type, individual gates at t-he end of the respective rows,each gate comprising a slidable block carrying a guiding pin, springssurrounding the respective pins for forcing the blocks outwardly andlips on the blocks limiting the outward movement.

10. In a printing machine, the combination of a. segmental type carrierhaving on its convex face a series of parallel channels, and individualend gates for the respective channels, means for holding them across theends oi the channels and means enabling them to be moved inwardly,substantially radially, to release the channels.
